Item-wise validity study of the Impact of Event Scale - Revised (IES-R): self-reported reactions of hospital personnel exposed to a stressful workplace.

Objective: Recent studies have revealed a heterogeneous prevalence and presentation of PTSD across countries. It is crucial to assess the methodological and item-level measurement factors that contribute to variations in mental disorder rates across cultures. This study aimed to investigate the traumatic experiences of hospital workers by employing item analysis of the Impact of Event Scale-Revised (IES-R).

Associations of comorbid headache disorders and depression with leisure-time physical activity among 14,088 adults in The Brazilian Longitudinal Study of Adult Health.

Background: While headache disorders are linked to low physical activity levels, the impact of depression on this relationship is unclear.

Objective: To assess how single and comorbid diagnoses of migraine and tension-type headache (TTH) interact with depression and leisure-time physical activity (LTPA) levels in The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

Methods: In this cross-sectional analysis based on the ELSA-Brasil baseline data, the relationship of migraine, TTH (both assessed with the International Classification of Headache Disorders, Second Edition), and depression (assessed with the Clinical Interview Schedule-Revised) with LTPA levels (International Physical Activity Questionnaire) was investigated by employing linear regression models.

Trajectories of anxiety, depression, and posttraumatic stress among healthcare workers during the COVID-19 pandemic: one-year monthly follow-up.

Objectives: This study aimed to assess longitudinal patterns of anxiety, depression, and posttraumatic stress symptoms, as well as their predictors, in a reference hospital workforce during the first two waves of the pandemic in Brazil.

Methods: Data were collected between July 2020 and June 2021 (N = 1,078). Anxiety, depression, and posttraumatic stress symptoms were assessed using three self-report scales (GAD-7, PHQ-9, IES-R).

Translation and Validation of the Brazilian Version of the European Obesity Academy Questionnaire on Patients' Motivations for Seeking Metabolic and Bariatric Surgery.

Purpose: Understanding patients' motives for undergoing metabolic and bariatric surgery (MBS) is key to managing postoperative expectations. We aimed to translate and validate the 14-item European Obesity Academy Questionnaire on Expectations about Surgical Treatment (EOAQ-EST) to Brazilian Portuguese for research and clinical use.

Materials And Methods: This study included a total of 198 candidates for MBS at a reference academic hospital in Brazil from January 2021 to February 2022.

Comprehensive investigation of factor structure and gender equivalence of the Beck Depression Inventory-II among nonclinical adolescents.

The Beck Depression Inventory-II (BDI-II) is a widely used tool for rating the severity of depressive symptoms. Studies on the factor structure of the BDI-II in adolescents have yielded controversial findings. Most studies have reported an oblique two-factor model that describes the 'cognitive' and 'somatic-affective' dimensions.

Does physical activity and inflammation mediate the job stress-headache relationship? A sequential mediation analysis in the ELSA-Brasil study.

Background: Evidence indicates that physical activity reduces stress and promote a myriad of health-enhancing effects through anti-inflammatory mechanisms. However, it is unknown whether these mechanisms interfere in the association between psychosocial job stress and headache disorders.

Objective: To test whether physical activity and its interplay with the systemic inflammation biomarkers high-sensitivity C-reactive protein (hs-CRP) and acute phase glycoproteins (GlycA) would mediate the associations between job stress and headache disorders.

The associations between daily reports of loneliness and psychotic experiences in the early risk stages for psychosis.

Aim: Bi-directional associations between loneliness and psychotic experiences (PEs) have been reported, but the mechanisms underlying these associations are unknown. This study aims to explore associations between daily reports of loneliness and PEs, and test differences in this association across young adult individuals at different levels of risk for psychosis.

Methods: We analysed 90-day diary data on loneliness and PEs from N = 96 participants (mean age 24.

Self-reported bruxism in patients with post-traumatic stress disorder.

Objective: The present study aimed to investigate the association between self-reported awake/sleep bruxism, and orofacial pain with post-traumatic stress disorder (PTSD).

Methods: A case-control study with a convenience sample was designed. Participants were recruited from a university-based Trauma Ambulatory.

Three Decades of Research on the Development of Ibogaine Treatment of Substance Use Disorders: A Scientometric Analysis.

Ibogaine is a natural psychoactive drug that has been investigated for its potential role in the treatment of substance use disorders since the mid-1960s. To evaluate the interest in ibogaine's use as a therapeutic agent, we performed a scientometric analysis covering the last three decades (1993-2002, 2003-2012, and 2013-2022). A complementary analysis was performed to select and describe published clinical trials and meta-analyses.

The performance of K6 as a screening tool for mood disorders: A population-based study of the São Paulo metropolitan area.

Aim: The use of screening instruments allows the detection of psychological and behavioural manifestations there are often not identified in users of health services. We evaluated the performance of the Kessler Psychological Distress Scale (K6) in identifying mood disorders (MD), using the Composite International Diagnostic Interview (CIDI) as gold-standard, in a population-based sample (n = 5037) of adult residents of metropolitan São Paulo.

Methods: Sensitivity, specificity, positive and negative predictive values, and accuracy were calculated to assess the performance of K6 in detecting 30-day CIDI MD.

Sex differences in the relationship between hepatic steatosis, mood and anxiety disorders.

Objective: To investigate the association between non-alcoholic fatty liver disease (NAFLD), alcoholic liver disease (ALD), mental symptoms (mood, anxiety disorders and distress) by sex.

Methods: This a cross-sectional study performed in working-age adults from a Health Promotion Center (primary care) in São Paulo, Brazil. Self-reported mental symptoms from rating scales (21-item Beck Anxiety Inventory, Patient Health Questionnaire-9, and K6 distress scale) were evaluated by hepatic steatosis (NAFLD and ALD).

Burden of disease due to amphetamines, cannabis, cocaine, and opioid use disorders in South America, 1990-2019: a systematic analysis of the Global Burden of Disease Study 2019.

Background: South America's substance use profile, poverty, income inequality, and cocaine-supplier role make it a unique place for substance use research. This study investigated the burden of disease attributable to amphetamine use disorder, cannabis use disorder (CAD), cocaine use disorder, and opioid use disorder (OUD) in South America from 1990 to 2019, on the basis of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019.
